it's alright. hate the guys color. if i was choosing the colors, for girls i'd say the cotton candy pink shirt (like you have) and maybe a darker pink or fuchsia for the illustration part, for guys maybe... white on kahki? kahki...howsit spelled? oh i dunno. also, i really don't think this doodle would work to well on a shirt as is. i think what could look kind of cool is maybe jjust the hand giving the peace sign, and then that's it.
:D
